Once the design is defined, the first prototype is developed. This means a great challenge for the engineers who have to develop the technical background of the design idea. Not only the ergonomics, the package and the effective functions of the vehicle must be constructed, but a multiplicity of technical requirements and demands must be checked and guaranteed.
